The objects (the small squares) can be selected/deselected. The small objects are contained in the larger container box. There can be several container boxes rowed up on the x axis.
I would appreciate suggestions on how to make the selection/deselection of the small squares as easy as possible, because when working on small objects like this it can really get fiddly and I feel that Fitt's law really isn't taken into consideration when it looks like my suggestion image.
The container box can be zoomed in horizontally so the dots get more space on the x axis, but the user shouldn't (in a perfect implementation) be forced to zoom in just to do the selection, and then zoom out to do other stuff that is easier in an zoomed out state.
I have been thinking of the OS X magnifying glass effect, but are there other ways of making the selection easier and less fiddly?
The design is for computers PC/Mac with mouse/mouse pad interaction.
